The role of sulfuric acid here is to create the nitronium ion ( + NO 2) which is the immediate electrophile reacting with the aromatic ring. The ring carbon attached to the carboxyl group is given the #1 location number. Note that a phenyl group is not the same as a benzyl group, the latter consisting of a phenyl group attached to a methyl group and a molecular formula of C 6 H 5 CH 2 −. As you will see later, aromatic rings do not really contain any double bonds, and many chemists prefer to represent the benzene ring as a hexagon with a circle inside it. Obviously, being cyclic isn’t a sufficient condition for aromaticity. Benzene is carcinogenic and has mostly been replaced as a solvent by the less dangerous methyl-substituted benzenes toluene and xylene. 5 C-C bonds. Benzene. It is a highly reactive substance. As their name indicates, polycyclic aromatic hydrocarbons are aromatic hydrocarbons which contain more than one benzenoid (i. Cyclic compounds are not all flat molecules. Benzene is one of the simplest (organic) aromatic hydrocarbons. The group of atoms remaining when a hydrogen atom is removed from an aromatic compound is called an aryl group. It's the most common aromatic hydrocarbon. The structure of benzene is represented as a hexagonal ring of carbon atoms, with alternating single and double bonds. The general formula for a cycloalkane is \(C_nH_{2n}\). A phenyl group consists of a benzene ring with one of its hydrogens removed.
